3d printing help

Dear Lazyweb, who among you has experience creating and printing non-flat 3D objects via Shapeways or similar?

I have something that I'd like to have 3d printed, but one of the things that Sketchup is incredibly shitty at is making things that don't have holes/leaks in them. The extrude/intersect commands fuck up all the time.

Can I send you my leaky .skp file and have you send me back something that Shapeways's printer won't completely fail on?
